The Art of Underwater Motion by Shawn Miller

As an underwater photographer there will be a time when you feel all your photographs look similar and you might lose interest for a while. Creating motion in still photographs will definitely give you a new challenge and purpose. The goal is to try to show some type of motion in a still photograph. The photographs emphasize the energy, power and or speed of the subject moving. Dramatic motion images will provide depth and variety to your portfolio.

Try panning or dragging the shutter underwater 

  • Move the camera in sync with the moving subject while the shutter stays open. A slow shutter speed will be necessary to achieve this.
  • Once you understand this technique try adding flash at the end of the exposure to freeze the motion of the subject (Rear curtain sync).
  • Get creative and add a spin the camera
